To determine the effect of recruitment on progenitor cells within the wound after administration of H5.020CMV.PDGF-β, we immunostained tissue biopsies for CD133 an antigen found on undifferentiated cell types such as endothelial progenitor cells. High and low power views of representative wound biopsies at (a) day 1, (b) day 3, and (c) day 28. Note more cells staining positive for CD133 at day 3 as compared to day 1 (P = 0.0015). Bar = low power: 500 µm, high power: 50 µm. CMV, cytomegalovirus; PDGF-β, platelet-derived growth factor-β.
